Thermoplastic	Thermosetting Plastic
Thermoplastic can be synthesized by the process called addition polymerization.	Thermosetting plastics are synthesized by condensation polymerization.
Thermoplastic is processed by injection moulding, extrusion process, blow moulding, thermoforming process, and rotational moulding.	Thermosetting Plastic is processed by compression moulding, reaction injection moulding.
Thermoplastics have secondary bonds between molecular chains.	Thermosetting plastics have primary bonds between molecular chains and held together by strong cross links.
Thermoplastics have low melting point and low tensile strength.	Thermosetting plastics have high melting point and tensile strength.
Thermoplastic is lower in molecular weight, compared to thermosetting plastic.	Thermosetting Plastic is high in molecular weight.

What effect does an electric current produce when flowing through a conducting liquid（or conducting solution）

Posted by Arneet Kang 6 years, 6 months ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 5 years, 6 months ago

When an electric current flows through the conducting solution, it causes a chemical reaction (or chemical change). Conduction of liquids depends on the ability of liquids to form ions. Some liquids such as oil or alcohol do not form ions and do not conduct electricity. The acetic acid separates into ions in water. So its solution conducts electricity. Most liquids that conduct electricity are solutions of acids, bases and salts. The passage of an electric current through a conducting liquid causes chemical reactions. The resulting effects are called chemical effects of currents.

A big definition of mode of nutrition

Posted by Priyanka Jain 6 years, 6 months ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 5 years, 10 months ago

Nutrition is defined as a process of intake of nutrients (like carbohydrates, fats, proteins, minerals, vitamins and water) by an organism as well as the utilisation of these nutrients by the organism. Nutrition is necessary for an organism as it provides energy to them from the food they eat. There are mainly two modes of nutrition: autotrophic nutrition and heterotrophic nutrition.

i. Autotrophic nutrition is that mode of nutrition in which an organism makes its own food from the simple inorganic materials like carbon dioxide and water present in the surroundings (with the help of sunlight energy).
Example: Green plants obtain food by autotrophic nutrition.

ii. Heterotrophic nutrition is that mode of nutrition in which an organism cannot make its own food from simple inorganic materials like carbon dioxide and water, and depends on other organisms for its food.
Example: All animals obtain food by heterotrophic nutrition.

These kind of waste products are broken down by the action of micro-organisms like Bacteria. This kind of waste decay and Decompose naturally and become harmless after some time. Biodegradable Waste Examples are Cattle Dung, Tea leaves, Wood, Grass, Fruit & Vegetables, Paper, Animal Bones. These turn into compost after decaying and act as Natural Fertilizers. They do not normally Pollute the Environment, but if present in a large quantity, those that cannot be Decomposed can pollute the Environment.

Non-Biodegradable Waste

These substances or type of waste material, (non-poisonous and harmless substances)cannot be broken down into a simpler form, they cannot be decomposed. Non-Biodegradable waste examples are Plastics, Ball Point Pen Refill, Polythene Bags, Glass Objects, Aluminum Cans, Iron Nails, Foil paper, Radioactive waste, to name a few.

A granary is a storehouse or room in a barn for threshed grain or animal feed. Ancient or primitive granaries are most often made out of pottery. Granaries are often built above the ground to keep the stored food away from mice and other animals. Granaries should be kept dry in order to prevent the spoilage of the harvest. Because, microbes can grow in damp environment.
